MACHINE FOR WEIGHING SACKS.

Specification of Letters Patent No. 32,826, dated May 14,11861manuallabor and consists of certain mechanism constituting a movable orfixed machine or apparatus for lifting and weighing or for only liftingloaded sacks and also merchandise. y

The mode heretofore commonly practiced of lifting sacks has been for twopersons one at each side of the sack to raise it from the place on whichit rests and a third person receives it on his back and conveys it away.By the use of this invention the person who has to carry the sack canwith a very little effort quickly raise it to the proper height fortaking it on his back.

The following is the construction of the aforesaid machine or apparatus:At the center of a skeleton framing a toothed rack is adjusted looselyin a vertical position and to the bottoni of said rack and fixed to oneside thereof a board or platform is connected to receive the sack orother weight to be raised; a toothed pinion takes or gears into theaforesaid rack and on the axis of said pinion another toothed wheel oflarger diameter than the pinion is keyed this wheel gears into anotherpinion, on the axis of which a fly wheel is keyed and to said wheel ahandle is fixed for imparting rotary niotion thereto the effect of whichis to transmit such said motion to the rack and platform aforesaid so asto raise the weight thereon. In cases where it is required to weigh thesack or other load to be lifted I propose to place a double scale beamat the lower part or bottom of the platform of the machine and sodispose said beam that the scale board or platform of the rack shallrest, on one end of said beam or beams and for this purpose the drivingpinion of the rack should be formed as to be capable of being thrown outof gear with the rack. It will appear obvious that by increasing theheight of the machine, weights may be raised from one story of awarehouse to the nextor from floor to floor as may be required.

In order to explain this invention as completely as possible I nowproceed to describe the best means I am acquainted with for carrying thesame into practical effect reference being had to the illustrative sheetof drawings hereunto annexed and to the numeral figures and letters ofreference marked thereon respectively as follows:

Description 0f the Drawings'.

At Sheet l, Figures l, 2, 3, el, 5, 6 respectively exhibit several viewsof a machine constructed according to this invention adapted for liftingand weighing loaded sacks and also merchandise. Fig. l is a sideelevation of said machine.; Fig. Q a front view thereof; Fig. 3 a backview; Fig. i a horizontal section through the line A B at Figs. l, 2, 3;Fig. 5 a vertical section through the line C D at Figs. 2 and Fig. G adetached portion hereinafter described and referred to. At- Sheet 2Figs, la, Q, 3 respectively exhibit several views of a modified form ofconstruction of machine adapted for lifting and weighing loaded sacksand also merchandise. Fig. lL is a front elevation of said machine; Fig.Qa a top plan view thereof without sack holder and platform; Fig'. 3"Lsection through A B at Figs. la and 21. At Sheet 3 Figs. T, S, i), i0,l1 exhibit several views of another form of machine constructedaccording to this invention adapted for lifting and weighing loadedsacks and also merchandise, this machine being a modification of themachines exhibited at Sheets 1 and 2 above mentioned. At Sheet 4 Figs.l2, 13, ll, l5 respectively exhibit several views of a machineconstructed according to this invention and adapted for lifting weightsor merchandise from one story or floor of a warehouse to others above bysuccessive lifts through the agency of mechanism arranged as hereafterdescribed for that purpose.

At each of the foregoing figures of each of the aforesaid sheets ofdrawings I em ploy similar characters of reference to denotecorresponding parts in so far as such parts appear or can be seen ateach of such said sheets of drawings and figures respectively.

At sheet l A is a framing; B a toothed llO rack of metal working inguides a a of the said framing; C metal bracket pieces fixed to thebottom of the rack B and supporting a skelet-on framing D on which restsa board E on which the weight to be Aweighed and raised is placed; Gr Gare short axes or spindles supported by and working in bearing pieces bZ) as at Fig. 5.

H is a toothed pinion capable of sliding on the spindle Gr so as to bebrought either into or out of gear with the teeth of thel rack B.

I is a toothed wheel keyed on the spindle Gr; this wheel gears into apinion K fixed on the spindle G; L a fiy wheel fixed on the spindle Gr;M- a handle fixed to the aforesaid fly wheel for imparting motion to themechanism.

N is a brake for lowering and retaining the board at any desired heightwhen required; O is a scale beam for weighing; c c the knife edges onwhich the beam oscillates; P a piece connected to the weighing` beams;the board rests upon the piece P in the act of weighing anything placedon said board, cl a rod fixed to the scale beams on which the Weightsare to be placed as required. (In weighing anything in the above machinecare must be taken to throw the pinion H out of gear with the rack B andalso to allow for the weight of the scale board and rack.)- I would hereobserve that when this machine is not required to weigh loaded sacks ormerchandise the weighing` apparatus above described may be dispensedwith and when this is the case the pinion H may then be permanently ingear with the teeth of the rack B and by removing the handle M andplacing a fast and loose pulley or riggers on the spindle G and passingan endless strap over the fast pulley or rigger the machine may then beworked by steam or other motive power instead of by manual labor. Thismachine may likewise be constructed as exhibited at Sheet 2 obL servingthat the principal points of difference between this last mentionedmachine andthat exhibited at Sheet l aforesaid consist in theconstruction of the sack holder and in the weighing mechanism. Asregards the sack holder it consists of a forked rod or bar l the lowerends whereof are afiixed to the plate or platform E which supports thesack. The upper end of the rod l is connected by a piece of metal 3 tothe top of the rack B and moves therewith. 4L, 5, 6 are hooks*thatmarked 4 is fixed to the rod l and those marked 5, 6 are looselyconnected to said rod. The said hooks are employed to support the headand sides of the sack and also to keep the mouth thereof open whendesired. As regards the weighing mechanism it diers from that beforedescribed and represented at Sheet l in the following respects-that isto say the plate or platform E which supports the sack is in this c asemade independent of the rack and mechanism employed to raise the sack.For this purpose I form a framing 7 supported by the knife edges S, 8.,I also affix to said framing two other knife edges 9, 9 for supportingthe plate or platform E and weight placed thereon during the operationof weighing.

l0 are pieces afiixed to the rack B for lifting the plate or platform Eand sack -or other weight placed thereon. In other respects themechanism is similar to that exhibited at Sheet l and the same lettersof reference are employed to denote corresponding parts wherever theyappear.'

The machine represented on Sheet 3 shows a modification of the sameinvention and represents a hand machine or truck the weighing mechanismbeing a steelyard working on a swivel fixed to the top of the machine asexhibited at Fig. S; e e are pinions gearing into the teeth of the racksf f formed on the skeleton framing g; 7L 7L are wheels respectivelyfixed on the axes of the 90 pinions e e for transmitting motion to theracks f f through the medium of the pinions c' i which gear into eachother and into the wheels z, 71,; 7c is a handle fixed on the axis ofone or other of the pinions c' for imparting motion to the mechanism; ZZ are handles and m m running wheels for moving the machine from oneplace to another n n are rods for holding the mouth of a sack open whenrequired.

The machine represents a modification of my invention when applied forraising weights through the different floors of a warehouse. Q is aframing of wood or metal carrying a platform u u on which the weights tobe raised are to be placed; R R are double racks fixed to said framingand working in suitable guides as at Fig. 15 placed at each of theuprights S S to which is also connected the following mechanism 110 tobe employed for raising the platform a u;

0, p, g, Q', 7", 1', s are a train of wheels and pinions mounted on axesworking in bearing pieces fixed to the upright S S; T a handle forimparting motion thereto; U a 115 brake wheel for lowering or retainingat any desired height the platform u u; V V are shafts extendingthroughout the entire height of the several floors or rooms of awarehouse. The extremities of said shafts 120 have beveled wheels tfixed thereon; the bevel wheel receives rotary motion from the bevelwheel 0 fixed onthe face of the wheel p and by means of connecting rodsa u cranks o and cross spindle -w corre- 125 sponding motion is impartedor transmitted to the wheelwork and upright shaft V at the other end ofthe platform u u by which both ends of the platform are raised together;I propose to 'fix wheel work in 130 each floor or room of the Warehousein which this machine is intended to be used and I make the racks R R ofsuch length that when the platform successivel)7 reaches the ceiling ofthe floor or room above the said racks shall take into the Wheels of theWheehvork therein and be thus lifted thereby as before in consequence ofthe shafts V V being,` continually rotating during the lifting of theplatform and in this manner and by these means I am enabled to raiseWeights from floor to Hoor of a Warehouse in a simple and eliicientmanner and by reversing the direction of motion of the Wheel- \vorl atthe basement floor of the Warehouse, the platform may be lowered usingthe brake Wheel or Wheels as desired. I propose to employY self actingsliding doors or shutters between each of the floors as ehibited at Fig.15 of Sheet 4 to prevent persons falling down the opening in saidfloors; the

rods Z fixed at each end of the platform act as Wedges to force open thesaid sliding` doors as the platform rises and descends and the Weightsclose said doors.

Having novv fully described and set forth the nature and object of mysaid invention of a machine' or apparatus for liftingand Weighing loadedsacks and also merchandise, together with the best means I am acquaintedwith for carrying the same into practical effect I would remark inconclusion that I claim as m v invention and desire to secure b vLetters Patent- A machine or apparatus of the construction substantiallyas above described, and for the purpose herein set forth.
